pci: tegra: Fix port information parsing
commit a62e84d7b1824a202dd incorrectly changed the tegra pci code to the
new fdtdec pci helpers. To get the device index of the root port, the
"reg" property should be parsed from the dtb (as was previously the
case).
With this patch i can successfully network boot my jetson tk1
